paraFoam

  • paraview is an open-source tool for CFD postprocessing
  • paraview is part of OpenFOAM installation
  • OpenFOAM application paraFoam is an extension of paraview for handling OpenFOAM test cases.
  • Application paraFoam is run typing command:
    # paraFoam

     

  • Work with paraview is the matter of practice. Detailed paraview analysis is beyond this course. We only mention that work with paraview is quite intuitive and provides all standard postprocessing tools and functions for CFD.

  • Mass conservation [*]
  • Momentum conservation [*]
  • where: Symbol $ \partial$ is partial derivative, $ {\textbf u}$ is velocity vector, $ t$ is time, $ p$ is static pressure [    Pa$ /($kg$ \,$   m$ ^{-3})=$m$ ^2$   s$ ^{-2}$], $ \mu$ is dynamic viscosity, $ \nu$ is kinematic viscosity and $ {\textbf g}$ is gravitational acceleration vector.
  • The whole system is closed with boundary conditions.
